ABOUT THE ROLE & TEAM

Responsible for ensuring highly reliable, scalable, and resilient production systems across cloud and on‑prem environments. Ensures high availability, disaster recovery readiness, and continuous improvement of service performance. Leads automation initiatives for provisioning, deployment, monitoring, and self‑healing to reduce manual effort and improve stability. Owns the event catalog, operational readiness, and reliability engineering practices to prevent recurrence of incidents and strengthen system resilience. Drives collaboration across Product, Engineering, T&E ICE, and Service Support Architects to ensure provider‑grade reliability and seamless operational integration of new releases.

WHAT YOU’LL DO

• Reliability Engineering
  • Design & maintain resilient systems ensuring high availability, scalability, and fault tolerance.
  • Ensure effective Disaster Recovery (DR), failover strategies, and resilience engineering across environments.
  • Improve platform reliability, observability, and performance across cloud and on‑premises systems.
  • Establish and maintain SLIs, SLOs, and error budgets to measure and govern service reliability.
  • Take ownership of production availability, capacity planning, performance tuning, and long‑term reliability initiatives.
• Automation, DevOps & NetOps
  • Drive automation for infrastructure provisioning, deployment, monitoring, and operational workflows.
  • Develop and implement auto‑remediation and self‑healing solutions to reduce manual intervention.
  • Manage CI/CD pipelines and Infrastructure as Code (IaC) frameworks for secure, repeatable deployments.
  • Implement and manage zero‑downtime deployment strategies (blue‑green, canary, rolling).
  • Support containerized and cloud‑native platforms including Kubernetes, Docker, and distributed systems.
  • Support NetOps tooling and network observability, ensuring visibility into network performance, events, and operational health.
• Incident, Problem & Event Management
  • Perform incident management, production troubleshooting, and lead RCA/PMIR (Postmortem) for critical outages.
  • Proactively identify reliability gaps, performance bottlenecks, and operational risks.
  • Optimize incident, event, and problem management processes to reduce MTTR and improve operational efficiency.
  • Define and maintain the event catalog, thresholds, and remediation workflows.
  • Develop event response protocols and ensure teams are trained for rapid incident handling.
• Observability & Monitoring
  • Build and maintain observability solutions using monitoring, logging, tracing, and alerting platforms.
  • Implement APM, distributed tracing, and proactive alerting to detect issues early.
  • Integrate network telemetry and NetOps monitoring tools into the overall observability stack.
  • Collaborate with stakeholders to improve event coverage and post‑event learning.
  • Experience with AI‑assisted observability, anomaly detection, and predictive alerting.
• Deployment & Operational Readiness
  • Own the quality of new release deployments for the PSO.
  • Conduct operational readiness assessments and manage deployment risk.
  • Ensure supportability for new applications, platform releases, and infrastructure changes.
  • Coordinate with internal/external stakeholders to drive continuous service improvement.
• Cross‑Functional Collaboration
  • Work closely with Development, Platform Engineering, Product, T&E ICE, and Service Support Architects to embed reliability best practices.
  • Collaborate with vendors and engineering teams to enhance system reliability and operational excellence.
  • Support new product productization as SGS technical expert and ensure operational readiness.
